\title{Manejo elemental de ruteadores cisco}
\begin{document}

\maketitle

\subsection{¿Porque cisco?}
Los ruteadores de Cisco dominan el mercado. Nosotros los vamos a utilizar en nuestros laboratorios. 
%\subsection{Router basic}
Los ruteadores cisco ejecutan Internetwork Operating System (IOS)
%IOS support everything anyone would ever want to do with router
La interface de los comandos es muy parecida a shell de unix. Tal como ayuda en linea, edición de la línea y historia.

%\subsection{Router modes}
%\subsection{Sessions}
%Sessions can be initiated from direct line (console, aux) or virtual line (vty)
%each line can be password protected (with separate passwords)
%it is possible to use user based authentication
%\subsection{Router modes (cont.)}
%User mode
%user can examine router status and operation.
%configuration cannot be viewed or altered from user mode
%prompt router>
%Privileged mode (“root”)
%complete control over the router (anything can be set or reset)
%configuration cannot be altered
%prompt router#
%\subsection{User modes (cont.)}
%Configuration mode
%used only for change of configuration
%not password protected from privileged mode
%privileged mode commands don’t have meaning in configuration mode
%most statements can be removed from the configuration with the prefix no (ex. no shutdown)
%prompt router(config)#
%\subsection{Router configurations}
%Two configurations:
%the active configuration (show running-config)
%the startup configuration (show startup-config)
%On line help
%\subsection{IOS have built-in help}
%at any point user may type ? and receive a list of what the executive expect to see next
%when used after character, help displays all command with the same prefix
%at the beginning of command line ? will give a list of all commands available in the current mode
%\subsection{Command line editing}
%all commands and strings can be abbreviated to their shortest unique prefix (ex. sh run)
%arrow keys will move the cursor to the left and right on the command line
%command history is accessed via up and down arrows
%previous commands can be edited and   re-entered
%\subsection{Command Line Editing}
%Advanced features:
%^A 	Move to left of line
%^B	Move to right of line
%^D 	Delete character under cursor
%^K 	Delete to end of line
%^F 	Move forward
%^B 	Move backward
%^P 	Move to previous line
%^N 	Move to next line
%\subsection{Network interfaces}
%each network interface is identified by type and number
%types can be abbreviated, numbers start at 0
%ethernet0	e0
%serial2		s2
%tokenring1	to1
%virtual interfaces for various purposes
%loopback
%tunnel
%vlan
%\subsection{Example}
%router> enable
%router# conf t
%router(config)# int e0
%router(config-if)# ip addr 10.0.0.10 255.255.255.0
%router(config-if)# no shut
%router(config-if)# ^z
%router# sho ip int e0
%\subsection{Useful commands}
%set the console password
%router(config)# line con 0
%router(config-line)# password mysecret
%set the vty passwords
%router(config-line)# line vty 0 4
%router(config-line)# password mysecret
%router(config-line)# exit
%set the enable password
%router(config)# enable password mysecret
%router(config)# service password-encryption
%router(config)# ^Z
%\subsection{Useful commands (cont.)}
%list all interfaces in a router
%router# show interface
%display running configuration
%router# show running-configuration
%save the configuration
%router# copy running-config startup-config
%display IOS information
%router# show version
%display contents of flash
%router# show flash
%display running network protocols
%router# show protocols
